§ 18.60.010 Purpose.

The central mixed use (CMU) zone supports active uses in the heart of the town center and historic city center, decreasing dependency on automobiles and creating a self-sustaining and interconnected geography with myriad services and attractions. Complementary commercial, civic, office and residential uses create a dynamic, mixed use environment. Preferred development incorporates active first-floor commercial uses with upper-story residential or office uses that increase the level of activity in the town center core, with multistory design that engages ground-floor users and passers-by while creating a sense of enclosure along the street. Building and site design function together to create a unified, inviting streetscape with attractive facades and functional design of entrances, lighting, and vehicle and bike parking areas. The CMU zone standards guide new development and redevelopment that create a walkable center focused on health and wellness, community and culture, and shopping and dining that serves the entire Cornelius community and attracts visitors from beyond the city.

§ 18.65.010 Purpose.

The corridor commercial (CC) zone serves as the gateway to the town center core, transitioning from a highway-oriented environment towards a main street character with smaller-scale businesses and attractions. Uses include commercial retail and services, along with opportunities for multi-family residential uses in a mixed use environment, civic uses including schools and parks as district anchors, and limited light industrial uses. The area is primarily defined by small, individual sites, with several large sites that connect and relate to the scale of surrounding uses. Pedestrian-scale development and streetscape standards inclusive of pedestrian and bicyclist amenities encourage users to experience the district on foot, while standards discourage automobile presence and auto-oriented uses. Development and redevelopment in this district creates a street presence along the N Adair and Baseline couplet, defined by primary entrances, building presence and landscaping. The CC zone standards guide new development and redevelopment that support active commercial and civic opportunities and an engaging street presence to welcome residents and visitors to the town center.

§ 18.75.010 Purpose.

The gateway mixed use (GMU) zone serves as the eastern anchor for the city's commercial core, with larger-format commercial, office, and residential opportunities in a mixed use environment. Uses include commercial retail and services, offices and employment opportunities, and multi-family residential uses, connected by open spaces, landscaping, and parks. The district welcomes users arriving by vehicle, bicycle, transit, and on foot by accommodating multiple modes of access and providing cross-circulation within the district through a mix of public and private streets, sidewalks, pathways, and connections. Development and redevelopment of the large lots that comprise this district is coordinated to create a cohesive, integrated form of development. Building presence, facade design, and building entrances are emphasized along the Baseline Street, N 19th/20th Avenue, N 26th Avenue, and future N Davis Street frontages to create a welcoming face for the district, with building height limited around the perimeter and concentrated in the interior of the district to increase compatibility with neighboring development. Landscaping, open space, and graduated height transition along the northern perimeter of the district create a low-impact, welcoming interface with the future Council Creek Regional Trail. The GMU zone standards support development of a mixed use district that meets city and regional needs for commercial, employment, and residential opportunities.

Methods of Reducing Flood Losses. In order to accomplish its purposes, this chapter includes methods and provisions for:
(1) 
Restricting or prohibiting development which is dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or in flood heights or velocities;
(2) 
Requiring that development vulnerable to floods, including facilities that serve such uses, be protected against flood damage at the time of initial construction;
(3) 
Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel floodwaters;
(4) 
Controlling filling, grading, dredging, and other development which may increase flood damage;
(5) 
Preventing or regulating construction of flood barriers which will unnaturally divert floodwaters or may increase flood hazards in other areas;
(6) 
Employing a standard of "no net loss" of natural and beneficial floodplain functions.

§ 18.90.020 Authority.

(A) 
The Basis for Establishing the Areas of Special Flood Hazard. The special flood hazard areas are identified by the Federal Insurance Administration in a scientific and engineering report entitled "The Flood Insurance Study for Washington County, Oregon and Incorporated Areas," Volumes 1 through 3, dated November 4, 2016 (Flood Insurance Study Number 41067CV001A, 41067CV002A and 41067CV003A), with accompanying flood insurance rate maps (FIRM) (Map Number 41067C0312E, 41067C0314E, 41067C0316E, 41067C0318E and 41067C0319E, dated November 4, 2016), are hereby adopted by reference and declared to be a part of this chapter. The flood insurance study and the FIRM are on file at the city of Cornelius community development department located at 1300 S. Kodiak Circle, Cornelius, OR 97113. The best available information for flood hazard area identification as outlined in this section shall be the basis for regulation.
(B) 
The floodplain administrator is the community development director or their designee.
(Ord. 2025-05 § 1 (Exh. A), 2025)

§ 18.90.030 General provisions.

(A) 
Warning and Disclaimer of Liability. The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by manmade or natural causes. This chapter does not imply that land outside the areas of special flood hazard or uses permitted within such areas is guaranteed to be free from flooding or flood damages. This chapter shall not create liability on the part of the city of Cornelius, any officer or employee thereof, or the Federal Insurance Administration, for any flood damages that result from reliance on this chapter or any administrative decision lawfully made hereunder.
(B) 
Abrogation and Severability. This chapter is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this chapter and another ordinance, easement, covenant, or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail. If any section, clause, sentence, or phrase of this chapter is held to be invalid or unconstitutional by any court of competent jurisdiction, then said holding shall in no way affect the validity of the remaining portions of this chapter.
(C) 
Violation and Penalties. Violations of the provisions of this chapter, inclusive, by failure to comply with any of its requirements or prohibitions shall constitute a misdemeanor. Any person, firm or corporation who violates any of these provisions contained in this chapter, inclusive, shall, upon conviction, be fined not more than $10,000 for each violation and in addition shall pay all costs and expenses incurred by the city in the prosecution of said violation. Nothing herein contained shall prevent the city from taking such other lawful action as necessary to prevent or remedy any violation.

(11) 
Documentation of how no net loss standards have been met per CMC § 18.90.070, No net loss standards.
(F) 
City Boundary Alterations. The floodplain administrator shall notify the Federal Insurance Administrator in writing whenever the boundaries of the city have been modified by annexation or the city has otherwise assumed authority or no longer has authority to adopt and enforce floodplain regulations for a particular area, to ensure that all flood hazard boundary maps and flood insurance rate maps accurately represent the city's boundaries. The notification will include a copy of a map of the city suitable for reproduction, clearly delineating the new corporate limits or new area for which the city has assumed or relinquished floodplain management regulatory authority.
(G) 
Watercourse Alterations. The floodplain administrator shall notify adjacent communities and the Department of Land Conservation and Development prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration.
(H) 
Requirement to Submit New Technical Data. The city's base flood elevations may increase or decrease resulting from physical changes affecting flooding conditions. As soon as practicable, but not later than six months after the date such information becomes available, the city must notify the Federal Insurance Administrator of the changes by submitting technical or scientific data in accordance with 44 CFR 65.4. The city shall require the applicant to submit such data and review fees required for compliance with the section through the applicable FEMA letter of map change process. The floodplain administrator shall require a conditional letter of map revision prior to the issuance of a floodplain development permit for proposed floodway encroachments that increase the base flood elevation and proposed development which increases the base flood elevation by more than one foot in areas where FEMA has provided base flood elevations but no floodway. An applicant shall notify FEMA within six months of project completion when an applicant has obtained a conditional letter of map revision from FEMA. This notification to FEMA shall be provided in a letter of map revision.
(I) 
Substantial Improvement and Substantial Damage Assessment and Determinations. The floodplain administrator shall:
(1) 
Conduct substantial improvement (as defined in CMC § 18.90.080, Definitions) reviews for all structural development proposal applications and maintain a record of substantial improvement calculations within permit files in accordance with subsection (E) of this section.
(2) 
Conduct substantial damage assessments when structures are damaged due to a natural hazard event or other causes.
(3) 
Make substantial damage determinations whenever structures within the area of special flood hazard (as established in CMC § 18.90.020(A)) are damaged to the extent that the cost of restoring the structure to its before damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred.
(J) 
Floodplain Permit Required. A floodplain permit shall be obtained before construction or development begins within any area horizontally within the area of special flood hazard established in CMC § 18.90.020(A) and shall include the information identified in CMC § 18.90.040, Floodplain permit application. The application shall be required for all structures including manufactured dwellings and all other development, as defined in CMC § 18.90.080, Definitions.
(K) 
No Net Loss. Adherent to NMFS 2016 Biological Opinion, mitigation is necessary to ensure no net loss in floodplain functions. FEMA's 2024 Draft Oregon Implementation Plan identifies proxies that provide measurable actions that can prevent the no net loss of the parent floodplain functions. These proxies include undeveloped spaces, pervious surfaces and trees to account for a no net loss in respective floodplain functions of floodplain storage, water quality, and vegetation. Mitigation of these proxies must be completed to ensure compliance with no net loss standards. No net loss applies to the net change in floodplain functions as compared to existing conditions at the time of the proposed development and mitigation must address the floodplain function that is directly impacted. The no net loss standards apply to all special flood hazard areas as defined in CMC § 18.90.020(A).
(Ord. 2025-05 § 1 (Exh. A), 2025)

§ 18.90.040 Floodplain permit application.

A floodplain permit shall be obtained before construction or development begins within any special flood hazard area. The permit shall be for all structures including manufactured dwellings, and for all development including fill and other development activities, as set forth in CMC § 18.90.080, Definitions.

(4) 
Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief;
(5) 
The community development director shall notify the applicant in writing that (a) the issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance up to amounts as high as $25.00 for $100.00 of insurance coverage and (b) such construction below the base flood level increases risks to life and property. Such notification shall be maintained with a record of all variance actions as required in subsection (C)(6) of this section; and

(c) 
Be certified by a registered professional engineer or architect that the design and methods of construction are in compliance with accepted standards of practice for meeting provisions of this subsection based on their development and/or review of the structural design, specifications and plans. Such certifications shall be provided to the community development director;
(d) 
Nonresidential structures that are elevated, not floodproofed, must meet the same standards for space below the lowest floor as described for residential construction in subsections (H)(2)(a) and (H)(2)(b) of this section;
(e) 
Applicants floodproofing nonresidential buildings shall be notified that flood insurance premiums will be based on rates that are one foot below the floodproofed level (e.g., a building constructed to the base flood level will be rated as one foot below that level).
(4) 
Manufactured Dwellings. Manufactured dwellings to be placed or substantially improved within an A, AE, AH or AO zone shall be elevated so that:
(a) 
Manufactured dwellings supported on solid foundation walls shall be constructed with flood openings that comply with subsection (H)(2)(a) of this section;
(b) 
The lowest floor of the manufactured home is elevated to a minimum of two feet above the base flood elevation; and

Access routes elevated to or above the level of the base flood elevation shall be provided to all critical facilities to the extent possible.
(L) 
Floodways. Located within special flood hazard areas established in CMC § 18.90.020(A) are areas designated as regulatory floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectiles, and erosion potential, the following provisions apply:
(1) 
Prohibit encroachments in the regulatory floodway including fill, new construction, substantial improvements, and other development unless:
(a) 
Certification is provided by a professional registered civil engineer demonstrating through hydrologic and hydraulic analysis, performed in accordance with standard engineering practice, that such encroachment shall not result in any increase in flood levels during the occurrence of the base flood discharge; or
(b) 
A city may permit encroachments within the adopted regulatory floodway that would result in an increase in base flood elevations; provided, that conditional approval has been obtained from the Federal Insurance Administrator through the conditional letter of map revision (CLOMR) application process, requirements established under 44 CFR 65.12 are fulfilled, and the encroachments comply with the no net loss standards in CMC § 18.90.070.
(2) 
If subsection (L)(1) of this section is satisfied, all new construction and substantial improvement shall comply with all applicable flood hazard reduction provisions of this section.
(3) 
Projects for stream habitat restoration may be permitted in the floodway provided the project complies with CMC § 18.90.070(F).
(M) 
Shallow Flooding. Shallow flooding areas appear on FIRMs as AO zones with depth designations. The base flood depths in these zones range from one to three feet where a clearly defined channel does not exist, or where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is usually characterized as sheet flow. In these areas the following provisions apply:
(1) 
Require adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures.
(2) 
Residential. New construction and substantial improvements of residential structures (including manufactured dwellings) within AO zones shall have the lowest floor (including basement) elevated above the highest grade adjacent to the building, a minimum of one foot above the depth number specified on the FIRM (at least two feet above the highest adjacent grade if no depth number is specified).
(3) 
Nonresidential. New construction and substantial improvements of nonresidential structures, including manufactured dwellings used for nonresidential purposes, within AO zones shall either:
(a) 
Have the lowest floor (including basement) elevated above the highest grade adjacent to the building, a minimum of one foot above the depth number specified on the FIRM (at least two feet above the highest adjacent grade if no depth number is specified); or
(b) 
Together with attendant utility and sanitary facilities, be completely floodproofed to one foot above the depth number specified on the FIRM so that any space below that level is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. If this method is used, compliance shall be certified by a registered professional engineer or architect.

§ 18.90.070 No net loss standards.

(A) 
General Provisions.
(1) 
No net loss of the proxies for the floodplain functions is required for development in the special flood hazard area that would reduce undeveloped space, increase impervious surface, or result in a loss of trees that are six-inch diameter at breast height (dbh) or greater. No net loss can be achieved by first avoiding negative effects to floodplain functions to the degree possible, then minimizing remaining effects, then replacing and/or otherwise compensating for, offsetting, or rectifying the residual adverse effects to the three floodplain functions.
(2) 
Compliance with no net loss for undeveloped space or impervious surface is preferred to occur prior to the loss of habitat function but, at a minimum, shall occur concurrent with the loss.
(3) 
No net loss must be provided within, in order of preference:
(a) 
The lot or parcel that floodplain functions were removed from;
(b) 
The same reach of the waterbody where the development is proposed; or
(c) 
The special flood hazard area within the same hydrologically connected area as the proposed development. Table 18.90.070(H) presents the no net loss ratios, which increase based on the preferences listed above.
(B) 
Undeveloped Space. Development proposals shall not reduce the fish-accessible and egress-able habitat and flood storage volume created by undeveloped space within the special flood hazard area. A development proposal with an activity that would impact undeveloped space shall achieve no net loss of fish-accessible and egress-able space and flood storage volume. Lost undeveloped space must be replaced with fish-accessible and egress-able compensatory volume based on the ratio in Table 18.90.070(H) and must be hydrologically connected to the waterbody that is the flooding source.
(C) 
Impervious Surfaces. Impervious surface mitigation shall be mitigated through any of the following:
(1) 
Development proposals shall not result in a net increase in impervious surface area within the special flood hazard area through the use of ratios prescribed in the table within subsection (H) of this section;
(2) 
Use low impact development or green infrastructure to infiltrate and treat stormwater produced by the new impervious surface, as documented by a qualified professional; or
(3) 
If prior methods are not feasible and documented by a qualified professional, stormwater retention is required to ensure no increase in peak volume or flow and to maximize infiltration, and treatment is required to minimize pollutant loading. See subsection (E) of this section for stormwater retention specifications.
(D) 
Trees. Development proposals shall result in no net loss of trees six inches dbh or greater within the special flood hazard area.
(1) 
Trees of or exceeding six inches dbh that are removed from the riparian buffer zone (RBZ), floodway, or RBZ-fringe must be replaced at the ratios in Table 18.90.070(H) and planted within the special flood hazard area.
(2) 
Replacement trees must be native species that would occur naturally in the Level III ecoregion of the impact area.
(E) 
Stormwater Management. Any development proposal that cannot mitigate as specified in subsections (C)(1) and (C)(2) of this section must include the following:
(1) 
Water quality (pollution reduction) treatment for post-construction stormwater runoff from any net increase in impervious area; and
(2) 
Water quantity treatment (retention or detention facilities) unless the outfall discharges into the ocean.
(3) 
Retention and detention facilities must:
(a) 
Limit discharge to match the predevelopment peak discharge rate (i.e., the discharge rate of the site based on its natural groundcover and grade before any development occurred) for the 10-year peak flow using a continuous simulation for flows between 50 percent of the two-year event and the 10-year flow event (annual series).
(b) 
Treat stormwater to remove sediment and pollutants from impervious surfaces such that at least 80 percent of the suspended solids are removed from the stormwater prior to discharging to the receiving water body.
(c) 
Be designed to not entrap fish.
(d) 
Be certified by a qualified professional.
(4) 
Detention facilities must be designed by a qualified professional and drain to the source of flooding.
(5) 
Stormwater treatment practices for multiparcel facilities, including subdivisions, shall have an enforceable operation and maintenance agreement to ensure the system functions as designed. This agreement will include:
(a) 
Access to stormwater treatment facilities at the site by the city of Cornelius for the purpose of inspection and repair.
(b) 
A legally binding document specifying the parties responsible for the proper maintenance of the stormwater treatment facilities. The agreement will be recorded and bind all subsequent purchasers and sellers even if they were not party to the original agreement.
(c) 
For stormwater controls that include vegetation and/or soil permeability, the operation and maintenance manual must include maintenance of these elements to maintain the functionality of the feature.
(d) 
The responsible party for the operation and maintenance of the stormwater facility shall have the operation and maintenance manual on site and available at all times. Records of the maintenance and repairs shall be retained and made available for inspection by the city of Cornelius for five years.
(F) 
Exempt Activities. The following activities are not subject to the no net loss standards; however, they may not be exempt from floodplain development permit requirements:
(1) 
Normal maintenance of structures, such as reroofing and replacing siding, provided there is no change in the footprint or expansion of the roof of the structure;
(2) 
Normal street, sidewalk, and road maintenance, including filling potholes, repaving, and installing signs and traffic signals, that does not alter contours, use or alters culverts and is less than six inches above grade. Exempt activities do not include expansion of paved areas;
(3) 
Routine maintenance of landscaping that does not involve grading, excavation or filling;
(4) 
Routine agricultural practices such as tilling, plowing, harvesting, soil amendments, and ditch cleaning that does not alter the ditch configuration provided the spoils are removed from the special flood hazard area or tilled into fields as a soil amendment;
(5) 
Routine silviculture practices (harvesting of trees), including hazardous fuels reduction and hazard tree removal as long as root balls are left in place;
(6) 
Removal of noxious weeds and hazard trees, and replacement of nonnative vegetation with native vegetation;
(7) 
Normal maintenance of above ground utilities and facilities, such as replacing downed power lines and utility poles, provided there is no net change in footprint;
(8) 
Normal maintenance of a levee or other flood control facility prescribed in the operations and maintenance plan for the levee or flood control facility. Normal maintenance does not include repair from flood damage, expansion of the prism, expansion of the face or toe or addition of protection on the face or toe with rock armor;
(9) 
Habitat restoration activities;
(10) 
Preemptive removal of documented susceptible trees to manage the spread of invasive species;
(11) 
Projects that are covered under consultations under Section 4(d), 7, or 10 of the Endangered Species Act (ESA).
(G) 
Riparian Buffer Zone (RBZ).
(1) 
The riparian buffer zone is measured from the ordinary high-water line of a fresh water body (lake; pond; ephemeral, intermittent or perennial stream) or mean higher-high water of a marine shoreline or tidally influenced river reach to 170 feet horizontally on both sides of the stream or inland of the MHHW. The riparian buffer zone includes the area between those outer boundaries on each side of the stream, including the stream channel.
(2) 
Functionally dependent uses are only subject to the no net loss standards of this section for development within the RBZ. Ancillary facilities that are associated with, but do not directly impact, the functionally dependent use in the RBZ (including manufacturing support facilities and restrooms) are subject to the beneficial gain standard in addition to the no net loss standard.
(3) 
Any other use of the RBZ requires a greater offset to achieve no net loss of floodplain functions on top of the no net loss standards described above, through the beneficial gain standard.
(4) 
Under FEMA's beneficial gain standard, an area within the same reach of the project and equivalent to five percent of the total project acres within the RBZ shall be planted with native herbaceous shrub and tree vegetation.

a. For example, if a development would create 1,000 square feet of new impervious surface, then 1,000 square feet new pervious surface would need to be created. However, if only 500 square feet can be created within the same reach, then the remaining 500 square feet created in a different reach would need to be 1,000 square feet because of the 200 percent multiplier.

AO is characterized as sheet flow.
"Area of special flood hazard"
means the land in the floodplain subject to a one percent or greater chance of flooding in any given year. It is shown on the flood insurance rate map (FIRM) as zone A, AO, AH, A1 – A30, AE, A99, and AR. "Special flood hazard area" is synonymous in meaning and definition with the phrase "area of special flood hazard."
"Base flood"

"Enhancement"
means the process of improving upon the natural functions and/or values of an area or feature which has been degraded by human activity.
"Fill"
means placement of any materials such as soil, gravel, crushed stone, or other materials that change the elevation of the floodplain. The placement of fill is considered "development."
"Fish accessible space"
means the volumetric space available to fish to access.
"Fish egress-able space"
means the volumetric space available to fish to exit or leave from.
"Flood" or "flooding"
means:
(1) 
A general and temporary condition of partial or complete inundation of normally dry land areas from:
(a) 
The overflow of inland waters; and/or
(b) 
The unusual and rapid accumulation or runoff of surface waters from any source;
(c) 
Mudslides (i.e., mudflows) which are proximately caused by flooding as defined by subsection (1)(b) of this definition and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current.
(2) 
The collapse or subsidence of land along a body of water as a result of erosion or undermining caused by currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature, such as flash flood or some similarly unusual and unforeseeable event which results in flooding defined in subsection (1)(a) of this definition.
"Flood elevation study"
means an examination, evaluation and determination of flood hazards and, if appropriate, corresponding water surface elevations, or an examination, evaluation and determination of mudslide (i.e., mudflow) and/or flood-related erosion hazards.
"Flood insurance rate map (FIRM)"
means the official map on which the Federal Emergency Management Agency has delineated both the special flood hazard areas and the risk premium zones applicable to the community.
"Flood insurance study"
(see also "flood elevation study") means the official report provided by the Federal Insurance Administration that includes flood profiles, the flood insurance rate map, and the water surface elevation of the base flood.
"Floodplain"
means any land area susceptible to being inundated by water from the sources specified in the "flood(ing)" definition.
"Floodplain management regulations"
means the provisions of this chapter in addition to the development and zoning code, building codes, health regulations, and other applications of police power. The term describes such state or local regulations, in any combination thereof, which provide standards for the purpose of flood damage prevention and reduction.
"Floodplain storage capacity"
means the volume of floodwater that an area of floodplain can hold during the one percent annual chance flood.
"Floodway, regulatory"
means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot. The regulatory floodway is delineated by the Federal Emergency Management Agency on the flood insurance study and flood insurance rate map.
"Footprint"
means the existing measurements of the structure related to the three floodplain functions and their proxies. The footprint related to floodplain storage refers to the volumetric amount of developed space measured from the existing ground level to the BFE, and the footprint related to water quality refers to the area of impervious surface that the structure creates.
"Functionally dependent use"
means a use which cannot perform its intended purposes unless it is located or carried out in proximity to water. The term includes only docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers, and ship building and ship repair facilities, but does not include long-term storage or related manufacturing facilities.
"Green infrastructure"
means the use of natural or human-made hydrological features to manage water and provide environmental and community benefits. Green infrastructure uses management approaches and technologies that use, enhance, and/or mimic the natural hydrologic cycle processes of infiltration, evapotranspiration, and reuse. At a large scale, it is an interconnected network of greenspace that conserves natural systems and provides assorted benefits to human populations. At a local scale, it manages stormwater by infiltrating it into the ground where it is generated using vegetation or porous surfaces, or by capturing it for later reuse. Green infrastructure practices can be used to achieve no net loss of pervious surface by creating infiltration of stormwater in an amount equal to or greater than the infiltration lost by the placement of new impervious surface.
"Habitat restoration activities"
means activities with the sole purpose of restoring habitat that have only temporary impacts and long-term benefits to habitat. Such projects cannot include ancillary structures such as a storage shed for maintenance equipment, must demonstrate that no rise in the BFE would occur as a result of the project and obtain a CLOMR and LOMR, and have obtained any other required permits (e.g., CWA Section 404 permit).
"Hazard trees"
means standing dead, dying or diseased trees or ones with a structural defect that makes it likely to fail in whole or in part and that present a potential hazard to a structure or as defined by the city.
"Highest adjacent grade"
means the highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure.
"Historic structure"
means any structure that is:
(1) 
Listed individually on the National Register of Historic Places or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;
(2) 
Certified or preliminarily determined by the Secretary of the Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined by the Secretary of the Interior to qualify as a registered historic district;
(3) 
Individually listed on the Oregon state inventory of historic places; or
(4) 
Individually listed on the city's inventory of historic places.
"Hydraulically equivalent elevation"
means a location (e.g., a site where no net loss standards are implemented that is approximately equivalent to one another (e.g., the impact site) relative to the same 100-year water surface elevation contour or base flood elevation. This may be estimated based on a point that is along the same approximate line perpendicular to the direction of flow.
"Hydrodynamic loads"
means loads induced on buildings or structures by the flow of floodwater moving at moderate or high velocity around the buildings or structures or parts thereof, above ground level when openings or conduits exist which allow the free flow of floodwaters. Hydrodynamic loads are basically of the lateral type and relate to direct impact loads by the moving mass of water, and to drag forces as the water flows around the obstruction.
"Hydrologically connected"
means the interconnection of ground water and surface water such that they constitute one water supply and use of either results in an impact to both.
"Hydrostatic loads"
means loads caused by water either above or below the ground surface, free or confined, which is either stagnant or moves at very low velocities, of up to five feet per second. These loads are equal to the product of the water pressure times the surface area on which the water acts. The pressure at any point is equal to the product of the unit weight of water (62.5 pounds per cubic foot) multiplied by the height of water above that point or by the height to which confined water would rise if free to do so.
"Impervious surface"
means a surface that cannot be penetrated by water and thereby prevents infiltration and increases the amount and rate of surface water runoff, leading to erosion of stream banks, degradation of habitat, and increased sediment loads in streams. Such surfaces can accumulate large amounts of pollutants that are then "flushed" into local water bodies during storms and can also interfere with recharge of groundwater and the base flows to water bodies.
"Letter of map change (LOMC)"
means an official FEMA determination, by letter, to amend or revise effective flood insurance rate maps and/or flood insurance studies. LOMCs are issued in the following categories:
(1) 
"Letter of map amendment (LOMA)"
means an amendment to the flood insurance rate maps based on technical data showing that an existing structure, parcel of land, or portion of a parcel of land that has not been elevated by fill (natural grade) was inadvertently included in the special flood hazard area because of an area of naturally high ground above the base flood.
(2) 
"Letter of map revision (LOMR)"
means:
(a) 
(b) 
A LOMR revises the current flood insurance rate map and/or flood insurance study to show changes to the floodplains, floodways or flood elevations. LOMRs are generally based on manmade alterations that affect the hydrologic or hydraulic characteristics of a flooding source and thus result in modification to the existing regulatory floodway, the effective base flood elevation, or the special flood hazard area. A conditional letter of map revision (CLOMR) may be approved by FEMA prior to issuing a permit to start a project if the project has a potential to affect the special flood hazard area.
"Low impact development,"
in the context of this chapter, means an approach to land development (or redevelopment) that works with nature to manage stormwater as close to its source as possible. It employs principles such as preserving and recreating natural landscape features and minimizing effective imperviousness to create functional and appealing site drainage that treats stormwater as a resource rather than a waste product. Low impact development refers to designing and implementing practices that can be employed at the site level to control stormwater and help replicate the predevelopment hydrology of the site. Low impact development helps achieve no net loss of pervious surface by infiltrating stormwater in an amount equal to or greater than the infiltration lost by the placement of new impervious surface. LID is a subset of green infrastructure.
"Lowest floor"
means the lowest floor of the lowest enclosed area (including basement). An unfinished or flood resistant enclosure, usable solely for parking of vehicles, building access, or storage, in an area other than a basement area, is not considered a building's lowest floor; provided, that such enclosure is not built so as to render the structure in violation of the applicable nonelevation design requirements of this chapter.
"Manufactured dwelling,"
in the context of this chapter, means a structure, transportable in one or more sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when attached to the required utilities. The term "manufactured dwelling" does not include a "recreational vehicle."
"Manufactured home park or subdivision,"
in the context of this chapter, means a parcel (or contiguous parcels) of land divided into two or more manufactured home lots for rent or sale.
"Mechanical equipment"
means electrical, heating, ventilation, plumbing, and air conditioning equipment, storage tanks and other service facilities.
"Mitigation"
means the reduction of adverse effects of a proposed project by considering, in the following order:
(1) 
Avoiding the impact altogether by not taking a certain action or parts of an action;
(2) 
Minimizing impacts by limiting the degree or magnitude of the action and its implementation;
(3) 
Rectifying the impact by repairing, rehabilitating, or restoring the affected environment;
(4) 
Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action by monitoring and taking appropriate measures;
(5) 
Mitigating for the impact by replacing or providing comparable substitute floodplain areas.
"New construction,"
in the context of this chapter, means structures for which the "start of construction" commenced on or after the effective date of the ordinance codified in this chapter.
"No net loss"
means a standard where adverse impacts must be avoided or offset through adherence to certain requirements so that there is no net change in function from the existing condition when a development application is submitted to the state, tribal, or local jurisdiction. The floodplain functions of floodplain storage, water quality, and vegetation must be maintained.
"Off site"
means mitigation occurring outside the project site.
"On site"
means mitigation occurring within the project site.
"Ordinary high water mark"
means the line on the shore established by the fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank; shelving; changes in the character of soil; destruction of terrestrial vegetation; the presence of litter and debris; or other appropriate means that consider the characteristics of the surrounding areas.
"Permanent foundation"
means a natural or manufactured support system to which a structure is anchored or attached. A "permanent foundation" is capable of resisting flood forces and may include posts, piles, poured concrete or reinforced block walls, properly compacted fill, or other systems of comparable flood resistivity and strength.
"Pervious surface"
means a surface that allows rain and snowmelt to seep into the soil and gravel below. Pervious surface may also be referred to as permeable surface.
"Qualified professional"
means an appropriate subject matter expert that is defined by the community.
"Reach"
means a section of stream or river along which similar hydrologic conditions exist, such as discharge, depth, area and slope. It can also be the length of a stream or river (with varying conditions) between major tributaries or two stream gages, or a length of river for which the characteristics are well described by readings at a single stream gage.
"Reconstruction"
means the repair of a structure damaged by any cause (not limited to flooding) without increasing the floor area of the structure.
"Recreational vehicle,"
in the context of this chapter, means a vehicle which is:
(1) 
Built on a single chassis;
(2) 
Four hundred square feet or less when measured at the largest horizontal projection;
(3) 
Designed to be self-propelled or permanently towable by a light duty truck; and
(4) 
Designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use.
"Rehabilitation"
means any improvements and repairs made to the interior and exterior of an existing structure that do not result in an increase in the ground floor area of the structure. Examples include remodeling a kitchen, gutting a structure and redoing the interior, or adding a second story.
"Restoration"
means the process of returning a disturbed or altered area or feature to a previously existing natural condition. Restoration activities reestablish the ecological structure, function, and/or diversity to that which occurred prior to impacts caused by human activity.

Riparian Buffer Zone (RBZ).
The outer boundary of the riparian buffer zone is measured from the ordinary high-water line of a fresh waterbody (lake; pond; ephemeral, intermittent, or perennial stream). The riparian buffer zone includes the area between these outer boundaries on each side of the stream, including the stream channel. Where the RBZ is larger than the special flood hazard area, the no net loss standards shall only apply to the area within the special flood hazard area.
"Riparian buffer zone fringe"
means the area outside the RBZ and floodway but still within the special flood hazard area.
"Silviculture"
means the art and science of controlling the establishment, growth, composition, health, and quality of forests and woodlands.
Special Flood Hazard Area (SFHA).
See "area of special flood hazard" for this definition.
"Start of construction"
includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, placement or other improvement was within 180 days of the permit date. The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers, or foundations or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.
"Structure"
means, for the purposes of this section, a walled and roofed building, a modular or temporary building, or a gas or liquid storage tank that is principally above ground.

The term includes structures which have incurred substantial damage, regardless of the actual repair work performed. The term does not include:
(1) 
Improvements to a structure to correct existing violations identified of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions; or
(2) 
Any alteration of a historic structure; provided, that the alteration would not preclude the structure's continued designation as a historic structure.
"Undeveloped space"
means the volume of flood capacity and fish-accessible/egress-able habitat from the existing ground to the base flood elevation that is undeveloped. Any form of development including, but not limited to, the addition of fill, structures, concrete structures (vaults or tanks), pilings, levees and dikes, or any other development that reduces flood storage volume and fish accessible/egress-able habitat must achieve no net loss.
"Variance"
means a grant of relief from the requirements of this chapter which permits construction in a manner that would otherwise be prohibited by this chapter.
"Violation"
means the failure of a structure or other development to be fully compliant with this chapter. A structure or development without the elevation certificate, other certifications, or other evidence of compliance with this chapter is presumed to be in violation until such time as that documentation is provided.
"Water dependent"
means a structure for commerce or industry which cannot exist in any other location and is dependent on the water by reason of the intrinsic nature of its operations.

(Ord. 878 § 1 (Exh. A), 2006; Code 2000 § 20.105)

§ 18.95.060 Resource protection exception process.

When planned development can occur that provides for the protection of the resource and permitted use through increased densities, clustered development or the transfer of development rights, a plan shall be submitted and approved through the administrative review, Type II process. Any associated partition, subdivision or design review applications that are required with the planned development shall be processed as a Type III application and reviewed by the planning commission.
(A) 
New residential, commercial and industrial development or substantial redevelopment requests involving deviation of natural resource protection requirements shall be reviewed through the conditional use permit/planned unit development process.
(B) 
Transfer of development rights (TDR) may be applied for as a conditional use permit/planned unit development (PUD). Development rights shall only be transferred between residential zones within the city.
(C) 
Proportional Increase in Density on an Individual Parcel. Increased density requests shall provide for a development equal or better than required by the base zone.
(1) 
Residential PUD. If a parcel loses between 10 and 50 percent of its area to natural resource protection setbacks, then the developer may apply for a conditional use permit/planned unit development (PUD).
(a) 
Meet the required setback and develop to the existing development standards and lot sizes of the underlying zone; or
(b) 
Meet the required setback and decrease the minimum lot size by 10 to 50 percent. The reduction in lot size, at a maximum shall be equivalent to percentage of the site lost to the natural resource protection setback.
For example: R-7 zone – 5 acre site, loses 1 acre to natural resource protection setback = 20% loss. The applicant may propose a development with lots 20% smaller than the R-7 lot size or 6,534 x 0.80 = 5,227 square foot lot size; and
(c) 
If a parcel loses more than 50 percent of its area to natural resource protection setbacks, then the developer shall only decrease the minimum lot size by a maximum of 50 percent.
For example: R-7 zone – 5 acre site, loses 3 acres to natural resource protection setback = 60% loss. The applicant shall only be permitted a development with lots 50% smaller than the R-7 lot size or 6,534 x 0.50 = 3,267 square foot lot size.
(2) 
Commercial or Industrial PUD. Natural resource protection setbacks may be applied to meet private landscaping requirements. New development or substantial redevelopment of properties where natural resource protection setbacks are required may request approval of a conditional use permit (CUP) and/or a planned unit development (PUD) to permit a 1:1 ratio exchange for square footage of native landscaped protection setback area in lieu of required private on site landscaping.
For example: A proposed industrial development property has 350 feet of street frontage, which requires 5 feet of landscaped area along the frontage or 1,750 square feet of landscaping. The industrial lot also abuts a significant natural resource for 35 lineal feet and is required to provide a 50-foot setback, which equals 1,750 square feet of natural resource protection. The applicant would be able to request the use of the natural resource protection setback area in lieu of the required private landscaping requirement through the conditional use permit process.
